Answer:
A. 58 square cm
Explanation:
From the composite figure,
A1 =
x base x height
=
x 2 x 3
= 3
![cm^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/rh1gjq8uygmsrcxnmtgq7j282r77jlctve.png)
A2 = length x width
= 8 x 2
= 16

A3 =
(a + b) h +
x base x height
=
(10 + 12) 3 +
x 2 x 3
=
(22) 3 + 3
= 11 x 3 + 3
A3 = 33 + 3
= 36
Total area = A1 + A2 + A3
= 3 + 16 + 36
= 58
